This title is... wrong.

It's entirely normal for stablecoins to fluctuate in minor ways like this [1], even USDC (which is literally backed by actual US dollars in a bank account) fluctuates +- 1 cent regularly. This is because these prices come from a variety of exchanges trading these currencies, with different supply pools.

Arbitrage remediates this very quickly (Tether, at time of writing, is at $1.00). Not defending Tether, it's backing is definitely sketchy, but there's no indication it's in trouble at the moment, and this being on the front page is incredulous to me since it seems to be just some random dudes pulling up Google Stocks and speculating?
